I enjoyed your video on Butt Wink and largely I tend to agree. But I think the main concern with the Butt Wink at the bottom of the squat is that if the spine is changing shapes under heavy load the lumbar discs become more vulnerable to injury. So even if within “normal range”, if the spine is moving from a small degree of extension into a small degree of flexion the nucleus of the disc will be pushed posteriorly causing increased wear and tear on the annular fibers that hold the disc together. So it is for this reason that keeping the pelvis in a relatively stable position becomes the best strategy for preventing injury over time.
